SPECIFICATION forming part of Letters Patent No. 717,21 1, dated December 30, 190'2.

Application filed October 29, 1900. Serial No. 34,797. `(No model.)

To @ZZ whom it may concern:

Be it known that LWALLACE S. JUDD, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful- The primary object of this invention is to provide a strong cheap pressed steel seat adapted to be secured by a single bolt to either kind of supporting-bar.

The invention consists of a pressed-steel seat having the characteristics hereinafter described, and pointed out definitely in the claim.

In the drawings, Figure l is a top plan of the seat; and Fig. 2 is a bottom plan of the middle portion thereof, the'latter View showing by dotted lines the positions of the supporting-bar. Fig. 3 is a longitudinal central section of the seat, and Fig. 4 is a transverse fragmentary section on the line 4 4 of Fig. l.

Referring to the parts by letters, B repre- This member apgitudinally-extended bar. In Fig. 4 this longitudinal bar appears in dotted lines, and, as stated, Fig. 2 illustrates it both longitudinal and transverse.

A represents the seat, which is made from a sheet-metal blank between suitable dies. As shown, it has the usual conguration of a pressed-steel seat, which need not here be particularized. Those characteristics constituting the present invention are found in the middle or bottom of the seatthat is to say, the part which is adapted to rest upon the supporting-bar and the parts of the seat immediately contiguous thereto. The middle part a of the seat is preferably depressed, so as to be capable of resting upon the supporting-bar B.

The holeo, through which the bolt C passes for fastening the seat to the said supportingbar, is formed through this middle part d namely, at the center of the seat. Two transversely-extended downwardly-embossed ribs a2 are formed in the bottom of the seat respectively in front of and behind said hole. The lower surfaces of these ribs lie in the same plane and are adapted to rest upon a longitudinally-extended supporting-bar B. Two

Vlongitudinally extended downwardly embossed ribs a3 are also formed in the bottom on opposite sides of the hole a. Their lower surfaces lie in the same plane preferably with the lower surfaces of the ribs a2 and of the center ci. These ribs 0.3 will rest upon the supporting-bar B when said bar is a transversely-extending bar. In either casethe seat is made fast to the bar B by the bolt C. At the intersections of the ribs co2 and a3 the four depressed bosses a4, a5, a6, and a7 are formed, which bosses extend below the lowersurfaces of the ribs a2 a3. These bosses will lie against the sides of the supporting-bar B whether the same be a longitudinal bar or a transverse bar-that is to say, the bosses d4 a6 will engage with one side of a longitudinal bar when the seat rests upon it, and the bosses a5 of will engage with the other side thereof, and thereby the turning of the seat upon said support will be prevented. The bosses a4 a5 will engage with one side of a transverse supportingbar when the seat rests upon it, andthe bosses a6 a7 will engage with the opposite side thereof and will perform the same offices as previously described. As shown in the drawings, there are two other longitudinal ribs as and a circular rib o9, all of which are embossed downwardly. These ribs may be omitted, if desired; but they give additional strength to the seat, and the circular rib, merging with the corner-bosses 0,4, a5, a, and a7, relieves the abruptness of the latter at the upper edges, allowing the metal to be more easily drawn.

Having `described my invention, I claim- A pressed steel seat having two downwardly-embossed straight longitudinal ribs and two downwardly-embossed straight transverse ribs at right angles to the longitudinal ribs, adownwardly-embossed circular rib surl In testimony whereof I hereunto affix my rounding the four ribs mentioned, and downsignature in the presence of two witnesses. wardly-ernbossed bosses at the intersections of said longitudinal and transverse ribs which VALLACE S' JUDD bosses merge above with said circular rib, but fitnessesz extend below it and below the other ribs Inen- ALBERT H.
